Application filed. April 8,

T0 aZZ whom it may concern.

Be it known that 1, CHARLES E. JorINsoN, a citizen of the United States, residing at Gillespie, M acoupin County,in the State of Illinois, have invented certain new and useful Improvements in Vacuum Samplers for Tanks of Refined Oil and Gasoline, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention consists in the novel construction and combination of parts hereinafter particularly described and distinctly claimed.

The object of my invention is to provide an improved sampler for tanks of refined oil and gasoline, whereby. an accurate sample of the oil or gasoline may .be taken from the bottom of the tank, or from anypoint intermediate of the bot-tom and the top of the contents of the tank; and which sampler shall be simple in construction and operation, efiicient and accurate in use, and of a low cost.

In the drawings, a

Fig. 1 is a side-elevation of a portion of the tank of a tank-car, with parts in section, and with other parts broken away; showing my invention in use therein.

Fig. 2 is a detail vertical section of my improved sampler detached from the tank after it has removed a sample of oil or gasoline, parts of the vertical hollow handle and vent-tube being broken away, to shorten the view thereof on account of the limited drafting space in which the drawing is made, and

Fig. 8 is a detail vertical section of the upper end of the filling-tube of the sampler, taken on the line 8-3 of Fig. 2.

In the present form of my sampler, 1 construct a small portable measure or can 1, preferably of metal, cylindrical in form, and of any size that is convenient, to be lowered into a tank 2 filled or partially filled with the oil or gasoline that is to be sampled.

Hereinafter I shall refer to the said measure or can 1 as the samplereceiver. It is made with a bottom 8 in which is formed a centrally-located filling-opening 4 in which is fixed the lower end of a short vertical filling-tube 5, which extends from said bottom to a point near the upper end of said receiver.

A spreader-cap 6 that is in the form of an Specification of Letters Patent.

inverted letter U in cross-section, is fixed upon the upper end of said filling-tube 5 by means of solder or other fastening-materials, so that said cap will extend across the upper end of said tube at a sufiicient distance therefrom to leave the exit thereat comparatively free and open, and yet intercept the upward discharge of oil and other liquids issuing from said tube, and deflect the same laterally, so that it will fall into the receiver and not be discharged upwardly into the combined handle and vent-tube 7 that is directly above and in alignment with said filling-tube of the sample-receiver 1.

Said combined handle and vent-tube 7 has its lower end fixed in a central flanged opening?) at the apex of the top or breast 9 of the said sample-receiver '1, and it is made of sufiicient length to enable the user to lower the receiver to the bottom of the tank, no matter what the size or depth of said tank may be, the said receiver being inserted through and withdrawn from the coveropening in the tank-dome or top 10 in taking a sample from said tank.

Said handle and vent-tube 7 is detachable from the receiver 1, by means of a common coupling 11 located near to the upper end of said receiver, and into which coupling the adjacent ends of threaded sections of said member 7 are screwed, so that after a sample of oil or other liquid has been taken from the tank the sample can be readily poured from said receiver 1 by detaching the longer upper section of said member 7, and pouring out the sample through the short section that is-fiXed centrally in the breasted top of said sample-receiver.

A common vent-cock 12 is screwed or otherwise fastened in the upper end of the said combined handle and vent-tube 7, to control the exit of air or gas thereat, in taking a sample.

The operation of my sampler will be readily apparent from the above description, but I point out the fact that the sample-receiver 1 should be empty, and the vent-cock 12 closed at the time of lowering said receiver into the oil or gasoline that is to be sampled.

With the parts thus arranged, when the receiver is lowered into the liquid to be sampled, no matter if a sample is to be taken from the bottom of the body of liquid, no liquid will enter said receiver until it has reached the required level or depth, as the air in said receiver cannot escape, and the liquid cannot enter the receiver, until the said vent-cock 12 has been opened.

Upon opening the vent-cock 12, with the receiver 1 submerged in the liquid to be sampled, the latter will rush into the lower end of the said fillingtube 5, will pass upwardly therein and strike the said spreadercap 6, and will thence pass into and fill the said receiver; and the cock 12 should be closed.

Then, the receiver should be drawn upwardly and removed from the tank 2, the closure of said vent-cock preventing evaporation or loss of the sample in the receiver and handle vent-tube 7 until the sample is to be removed from the receiver, which can readily be accomplished by unscrewing the 7 coupling 11 from the short section of member 7 which is fixed to the top or breast 9 of said receiver, and then pouring out the sample into whatever kind of a bottle or testing-instrument that is used in preserving or testing said sample.

I do not limit myself to the exact details of the various parts shown in the drawing, as it will be readily understood that the same may be changed by a skilled workman without departing from the spirit and scope of my invention.

A sampler for refined oils and gasoline,

bottom of the tank containing the liquid to f be sampled through an opening in the top of said tank; a vertical filling-tube, the lower end of which is fixed in said entrance-opening in the lower end of said sample-receiver, and which filling-tube extends upwardly to a point near the top 01 said receiver upon the interior of the latter; a spreader-cap fixed over the open upper end of said fillingtube, and arranged to prevent the entering liquid from being forced upwardly directly into the open lower end of said combined handle and vent-tube; and a vent-device to control the exit of air from said receiver after same has been lowered into the liquid to be sampled.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
